A full stack developer is essentially a developer who has functional knowledge of all layers of creating a web application (front end, back end and database) but has expertise in certain specific areas. A full stack developer generally makes working easier for his or her entire team because of their familiarity of all layers.
A lot of companies like Facebook are gradually increasing the hiring of full stack developers and these smart people visualize the entire product from all angles before they get started with the building. This is when a great product gets built in a lesser amount of time.
Let’s take a look at what the layers of the full stack are and what the roles of the full stack developer are in them:
- Business Logic:
- Understanding the core of the value the application will provide
- Probably knowledge of frameworks
- A strong basis of object oriented skills
- Understanding the requirements of the business as well as the customer
- Here is when the blurring of the architecture line happens. A full stack developer has a general idea of the architecture is needed.
- A full stack developer will usually have a good grasp of what is actually going on in the field when the software is being used by the customer and the customers’ customers.
- They also have a good grasp of the business.
- Network, Server and Hosting Environments
- This includes the understanding of what can cause bugs and why, without taking any resources for granted.
- Appropriate use of cloud storage, file system, network resources, and a thorough understanding of data availability and redundancy is required.
- How the application can scale even if there are constraints in terms of the hardware.
- Taking into consideration of race conditions and multi-threading.
- Ability to work along with DevOps. This system provides logging capabilities and useful error messages. DevOps gets the look at messages even before you do, so make sure this is taken into consideration.
- Data Modeling
- If the data model turns out with flaws, the higher layers and business logic can begin to require sometimes strange coding in order to compensate for corner cases that the data model may not properly cover.
- Knowing how to make a reasonably normalized relational model that is complete with indexes, lookup tables, views, foreign keys etc.
- Expected to be familiar with non-relational data stores and know where they can do better than relational data stores.
- API layer/MVC
- The operation of the outside world against the data model and the business logic.
- Frameworks that need to be heavily used
- Full stack developers have the ability to write consistent, clear with simplistic interfaces.
- User Interface
- Full stack developers have an understanding on how to make a readable layout but at the same time, they can also acknowledge the need for engaging a graphic designer when needed. Either way, the priority is a great visual design.
- Can include the mastery of CSS/HTML5
- Full stack developers can step back and have a look at the process to correct anything that needs more clicks or more steps in order to bring it down to a lesser number of clicks.
- Full stack developers can think about how the UI design gets affected every time the backend needs change.
Full stack developers also have a general idea of security at all layers. They also have the ability to write quality unit tests.
This is why all start-ups are going to need full stack developers who understand the whole spectrum and are versatile. You think you may have it in you to become a full stack developer? Let IIHT help you decide if this is a good career option for you!
